Re: (ET) ok, not the fusible link

[Michael S Briggs <msbriggs alberti unh edu>]

Dammit! Ok, apparently it's NOT fixed. I was able to drive out to the 
yard. I was able to turn on the mower deck while sitting still. As soon as 
I then tried moving, with the deck on, the drive motor cut out. The blades 
kept moving until I turned the deck off - and of course won't start back 
up (the blades or anything else).
	Seems to be the same symptoms as I had before *after* replacing 
the blown fuse and soldering back together the fuse block. (the fuse 
didn't blow this time)
       When I engage the power disconnect and try driving, I hear a click, 
the power use gauge jumps up into the yellow, but nothing happens (no 
drive motor engaged). When I try engaging the PTO (mower deck), nothing 
happens (no power use change, no mower deck coming on).
	It seems like there's some short in the drive motor circuit 
somewhere. Just before it cut down, I engaged the blades, and the power 
use spiked to red as it started spinning the blades, then came down to the 
high end of the green (those gator blades seem to use a lot of power - I 
think I'll switch back to the regular ones). When I then tried driving, 
with the mower deck on, the power use gauge spiked red, and I moved about 
an inch before the drive motor cut out.
        I'll start looking through the drive motor line. Any ideas?

Thanks,
Mike
